Abstract

Abstract A method of packaging, and the package so produced, for maintaining living organisms viable for a long period of time. The living organisms, such as bacteria, fungi, algae, etc., are mixed with a carrier, such as peat. The organism-carrier mixture is then disposed in a package, such as a heat-sealable plastic envelope, and a gaseous atmosphere is provided in the package effective to induce and maintain substantial nonvegatative state formation of the organisms. Some organisms will form cysts, others spores, but whatever nonvegetative state is assumed, the organisms will be much less susceptible to heat, cold, starvation, and other adverse environmental factors. Suitable gaseous atmospheres include nitrogen, helium, and argon gases. The package is then sealed to prevent contamination of the atmosphere therein.

Claims Analysis

Total Claims: 27
Claim 1
Independent Claim 86 words
A method of packaging living organisms consisting essentially of the steps of mixing the living organisms with a carrier comprising substantially granular material suitable for maintaining the organisms in a viable condition over a long period of time, disposing the organism-carrier mixture in a package, providing a gaseous atmosphere in the package effective to induce and maintain substantial nonvegetative state formation of the organisms, and sealing the package to prevent contamination of the atmosphere therein until breakage of the seal just before use of the organisms.
Claim 2
Independent Claim 86 words
A method of packaging living organisms consisting essentially of the steps of mixing the living organisms with a carrier comprising substantially granular material suitable for maintaining the organisms in a viable condition over a long period of time, disposing the organism-carrier mixture in a package, providing a gaseous atmosphere in the package effective to induce and maintain substantial nonvegetative state formation of the organisms, and sealing the package to prevent contamination of the atmosphere therein until breakage of the seal just before use of the organisms.
Claim 3
Dependent Claim 26 words
A method as recited in claim 1 wherein the package comprises heat-sealable flexible sheet material, and wherein said sealing step is practiced by heat-sealing the package.
Claim 4
Dependent Claim 30 words
A method as recited in claim 1 wherein said atmosphere providing step is accomplished by providing an atmosphere selected from the group consisting essentially of nitrogen, helium, and argon gases.
Claim 5
Dependent Claim 35 words
A method as recited in claim 1 wherein the living organisms are selected from the group consisting of the genera Azotobacter, Achromobacter, Beijerinckia, Clostridium, Pseudomonas, Bacillus, Rhizobium, Trichoderma, Anabaena, Cylindrospermum, Nostoc, Volvox, Oscillaria, and Lactobacillus.
Claim 6
Dependent Claim 29 words
A method as recited in claim 4 wherein the living organisms selected from the genus Azotobacter are selected from the group consisting of the species vinelandii, agile, and chroococcum.
Claim 7
Dependent Claim 32 words
A method as recited in claim 4 wherein the living organisms selected from the genus Rhizobium are selected from the group consisting of the species leguminosarum, phaseoli, trifoli, meliloti, lupini, and juponicum.
Claim 8
Dependent Claim 21 words
A method as recited in claim 1 wherein the carrier is selected from the group consisting essentially of peat and whey.
Claim 9
Dependent Claim 37 words
A method as recited in claim 1 comprising the further steps of breaking the seal of and opening the package after an extended storage period, and applying the organisms with the carrier to plant roots or seeds.
Claim 10
Dependent Claim 76 words
A package of living organisms consisting essentially of living organisms mixed with a carrier comprising a substantially granular material suitable for maintaining the organisms in a viable condition over a long period of time, gaseous atmosphere means for inducing and maintaining substantial nonvegetative state formation of the organisms, and a sealed envelope surrounding said carrier, organisms, and atmosphere for preventing contamination of said atmosphere until breakage of the envelope seal just before use of the organism.
Claim 11
Dependent Claim 76 words
A package of living organisms consisting essentially of living organisms mixed with a carrier comprising a substantially granular material suitable for maintaining the organisms in a viable condition over a long period of time, gaseous atmosphere means for inducing and maintaining substantial nonvegetative state formation of the organisms, and a sealed envelope surrounding said carrier, organisms, and atmosphere for preventing contamination of said atmosphere until breakage of the envelope seal just before use of the organism.
Claim 12
Dependent Claim 26 words
A package as recited in claim 9 wherein said atmosphere means comprises a gas selected from the group consisting essentially of nitrogen, helium and argon gases.
Claim 13
Dependent Claim 18 words
